摘要： A method of manufacturing a multilayer ceramic device capable of obtaining a superior multilayer ceramic device even if the number of layers increases or even if the multilayer ceramic device is upsized, and specifically suitable for manufacturing a multilayer piezoelectric device is provided. After a laminate in which ceramic precursor layers including a raw material of a ceramic layer and internal electrode precursor layers including copper metal as a raw material of an internal electrode layer are alternately stacked is formed, the laminate is heated to degrease the laminate. At this time, an atmospheric gas including an inert gas, 7 mol % to 50 mol % of water vapor, and, if necessary, hydrogen is used to adjust an oxygen partial pressure within a range of p(O2)≦(25331×Kp)2/3, where p(O2) represents an oxygen partial pressure; Kp represents a water dissociation equilibrium constant; and the pressure unit is Pa. Thereby, while the oxidation of copper metal can be prevented, a binder can be sufficiently decomposed and removed, and residual carbon can be reduced.
